- upon a. pipe vide a clamp whereby the point through which Be it known that I, GEOBGEHAGKER, acitizen of the United States, residing at St: Lo'uis,.

State of Missouri, have invented ciertain new vices, of which the following is aspecification containingfa full, clear, and exact description, :ference being had to the accompanying drawings, forming a part hereof.

and useful Improvements in Clamping. Dev 0n the pipe, that portion of the pipe is provi ed with screw-threads, as shown in Fig. 1, and the dey'ic'e to eclamped upon said pipe, which is indicated by vice at any 'locati0n.u

the letter A, is placed thereon. The washers- 5 are then placed one on each side thereof and pipe 11 and This invention relatesto improvements in a I the recesses 6, tightly compresslng said wash.-

;lamping device; and it consists in the novel arrangement, construction, and combination andclaimed. g

The ObJEClI- of this invention is to construct a device whereby-any obge'ct may he clamped out necessarily threading the entire pipe or rod.

A'further object of this invention is to prothe pipe is passed ismade-secure and water and air tight.

Figure 1 1s a vertical-sectional view of my In the construction of myimproved inyention I provide washers 5, the outer surface of 1 together by the recesses 1n the washers, subwhich is provided with a recess 6, arranged in shape to correspond with the shape of the nut 7. The other face of the washers is also provided with recesses 8. in which packing 9 is adapted to be.pl aced when so desired. The split nut 7 isconstructed of two parts formed by splitting the ordinary nut longitudinally and transversely of the threads, as shown in Fig: 4:, each part beingprovided with the internal screw-threads 10.

The pipe 11, to which the ciamping device is secured, is provided with screw-threads 12.

or rod at any given point with .of parts, as will, befully here'inafter deseribed' improved clamping device,'showing the same 1 I l l "the packing 9 placed in position. The split nuts are then placed over the threads of the said nuts turned in opposite direction. .By this'operation they, will pass into .turned in opposite directlons to that when a-pplied, and when sufficiently loose'the washers the nuts will fall are pressed inwardly and same-be' from their location on account of the ing halved.

The part referred to by the letter A in the drawings may represent the side of a tanlt, the bottom of a. barrel, orany object through. which a long pipe is eittended.

Having fully described my invention, what I claim is l. A clamping device comprising a threaded rod, two oppositely-threa'ded nuts split longi tudinally in halves, washers recessed to receive the bases of the nuts, the nuts being adapted to be screwed toward each other upon the rod to hold an interveningobject in placeupon the rod, the halves of the nuts being held stantially sis-described.

Q. A device of the ClilSS-LlESCl'lbLLL comprising awasher, a pipe, recesses formed in said washer, packing material placed in one of said recesses, as'piit nut adapted to be placed -upon' a threaded portion of said pipe and to lodge within the other recess of the washer" when The operation of my invention is as follows: 1 ing a split nut, a pipe, threads formed on a When it is desired to apply my clamping del portion oi said pipe. washers having recesses,
